The image above represents shielding factor.

To compute for shielding factor, two essential parameter are needed and these parameters are **coil radius (R _{s})** and

**shielding depth (L).**

The formula for calculating the shielding factor:

ε = ^{Rs} / _{L}

Where:

ε = Shielding Factor

R_{s} = Coil Radius

L = Shielding Depth

Let’s solve an example;

Find the shielding factor when the coil radius is 11 and the shielding depth is 21.

This implies that;

R_{s} = Coil Radius = 11

L = Shielding Depth = 21

ε = ^{Rs} / _{L}

ε = ^{11} / _{21}

ε = 0.52

Therefore, the **shielding factor **is **0.52.**

**Calculating for the Coil Radius when the Shielding Factor and the Shielding Depth is Given.**

R_{s} = ε x L

Where;

R_{s} = Coil Radius

ε = Shielding Factor

L = Shielding Depth

Let’s solve an example;

Given that the shielding factor is 30 and the shielding depth is 5. Find the coil radius?

This implies that;

ε = Shielding Factor = 30

L = Shielding Depth = 5

R_{s} = ε x L

R_{s} = 30 x 5

R_{s} = 150

Therefore, the **coil radius **is **150.**
